We are pausing our live coverage of Russia's invasion of Ukraine.
Today, Rishi Sunak announced a £500m military aid package for Ukraine - the UK's largest military pledge to the country.
In a speech in Warsaw, Poland, Mr Sunak said: "An investment in Ukraine is an investment in our security."
The prime minister also said he would put the UK's own defence industry "on a war footing" as he confirmed an increase in defence spending to 2.5% of national income by 2030.
The announcements were praised by NATO secretary-general Jens Stoltenberg, who said the UK was "leading by example" for other NATO countries.
Potential Russian summer offensive
Elsewhere, a commander from Ukraine's National Guard has said Russia is planning "unpleasant surprises" in a potential summer offensive.
Oleksandr Pivnenko told news outlet Liga Net that, as part of this, the National Guard does not rule out Russian attempts to target Kharkiv - the country's second-largest city.
Kharkiv and the surrounding region have recently been the focus of recent attacks from Moscow, having experienced the most intense strikes.
Russia vows to attack 'Western weapons stores'
The Russian defence minister said that when the US military aid package for Ukraine becomes law, Russia will "increase the intensity of attacks on logistics centres and storage bases for Western weapons".
Ukraine is set to receive provisions worth nearly $61bn.
The bill will later be voted on in the US Senate, where it is likely to pass. Joe Biden has promised to sign it into law immediately after this.
